DEVICE FOR STBAIGHTENING WHEELS.

Application filed November lily invention pertains to devices designed priniiarily for straightening disk wheels, the object being to provide an effective device for removing the dents and displacements from the disk of an automobile wheel, and truing the same up generally.

As is well known, the disk wheel for automobiles is rapidly gaining in popularity, and an eiiicient device of this character has come to be a really indispensable factor or unit in every well equipped garage and automobile repair shop.

In the drawings accompanying the application, Figure 1 is a top plan view, with the wheel in position to be operated upon; Fig ure 2 is a side elevation, also showing the wheel. in position; Figure 3 is an end view; and Figure 1 is a detail sectional view on line a d Figure 2, illustrating the mounting of one of the operating screws.

1-1 represent the posts of the framework, and 2 the bracings or reinforcements of the same.

Rigidly secured to the upper portion of the posts are the oppositely disposed transverse bars 33, which also form a part of the framework, as well as serving to support the guide-ways described in the next paragraph. I

Rigidly secured to the transverse bars 3, one above and the other below, and ad jacent what may be termed the front of the machine, are the two angle irons 1 1, forming the longitudinal guide-way 5.

Slidably mounted upon said transverse bars 3-3, adjacent the rear of the machine, are similar angle bars 6-6, forming the longitudinal guide-way '7, and the bars 3-3 are provided with holes 8 for the reception of pins 9 to hold the guide-way 7 in adjusted position.

Slidably moun ed in the guide-way is the head-block 10 provided with a threaded central opening 11, adapted to engage the operating screw 12, and carrying at its inner end the flanges 18-13, adapted to engage the inner face of the angle irons 1- 1 to hold the head-block against stress or pressure of the operating screw 12. r

A similar head-block is also mounted in the longitudinal guide-way 7, within which is mounted the opposing operating screw 14.

Smbracing or enclosing the head-block 10 is the loop or link 15, provided in its outer end with a. central opening for the loose re ception of screw 12, while its inner end 16 is 14-, 1925. Serial no. caorr.

solid and is engaged by the inner end of screw 12.

A duplicate loop or link 17 is similarly secured to the head-block mounted in the guide-way 7 at the rear of the machine.

Rigidly secured to the posts 1-1 and beneath the angle irons 1-d and 66, respectively, are oppositely disposed longitudinal bars 18 (rear bar not shown). Each of these bars is provided in its upper edge with a series of notches 19, in which are mounted the transverse rods 20, which serve as adjustable supports for the wheel, in order that the lat ter may be held in the desired position to be operated upon.

21-21 represent removable blocks, suggesting how the same may be placed between the angle irons or bars 1 and 6 and the wheel, to hold or support the latter rigidly against pressure of the operating screw.

In the wheel W in position, as shown in Figure 1, the solid lines of the disk 21 inclicate the dents or displacements in the same, while the dotted lines indicate the correct shape or outline of the disk.

In the operation of my machine, the wheel is first placed in position, as shown in Figures 1 and 2, resting upon the transverse bars properly adjusted to hold the wheel in the necessary position to bring the contact of the operating screw 12 and 141 (one or both) with the disk at the point of bend or displacement which it is desired to cor rect, after which the proper operating screw (one or both) is turned'sufficiently to effect such correction. V

While two operating screws make the machine much more effective and satisfactory in its operation, it is obvious that it can be used with only one guideway, head-block and operating screw, by providing sufficient back support for the wheel to resist the pressure of the operating screw from the front,

I claim:

1. In a device for straightening wheels, a rigid frame-Work, a pair of oppositely disposed, aarallel guide-ways in said framework, a head-block mounted in each of said guide-ways, each of said head-blocks being provided with a threaded central opening, an operating screw mounted in eachof said openings and adapted to engage the wheel, and means for holding the wheel in the desired position in the frame-work.

2. In a device for straightening wheels, a rigid frame-work, a longitudinal guide-way adjacent the front of said frame-Work, a head-block slidably mounted in said guideway and provided With a threaded central opening, an operating screw mounted in said opening and adapted to engage the Wheel, a longitudinal guide-way adjacent the rear vof said frame-Work and laterally adjustable, a llGdd-blOCk slidably mounted in said guideway and provided With a threaded central opening, an operating screw mounted in said opening and adapted to engage the wheel, and means for holding the Wheel in the desired position in the framework.

.In testimony whereof, I have hereunto affixed my signature.
